Purpose / Context - Sustainability has become an important issue in building construction sector. The tools of sustainable building assessment have been developed to evaluate the environmental impacts of buildings around the world. Chinese green building assessment tool (GB) was established later than other tools from developed countries. Therefore, the aim of this paper is to improve the evaluation method in Chinese green building assessment .Two famous assessment tools of BREEAM (2011) from the UK and LEEDv4 from the US are taken as examples for comparison analysis. Methodology / Approach – The method of this research is to investigate the similarities and differ-ences of assessment criteria and indicators among three assessment tools by conducting a compari-son with other countries' green building standards. Results –The results have found that when compared with major sustainable development catego-ries, there is no obvious difference. However, in sub-criteria of each category, when compared with BREEAM and LEED, GB tool does not take more items into consideration and lacks more quantitative criteria, such as classifying building types, transport in sustainable site and energy effi-cient operation. Since each assessment tool has its own specialty to satisfy its local condition, GB assessment tool will follow the local standards and strategies to improve the deficiency of the original evaluation criteria. Originality – This research provides constructive suggestions of the essential sustainable criteria for the future development of Chinese green building assessment.
